Answer:
Arc length s = 15.3 inches
Step-by-step explanation:
We know that length of an arc that subtends an angle θ radians at the center is given by

where
r is the radius of the circle
θ is the angle subtended in radians
Thus applying values we get 
thus s = 15.3 inches

Answer:
1. $0.80 or 80 cents
2. 1.25 meters
Step-by-step explanation:
The equation p=0.8L represents the price p (in dollars) of a piece of nylon rope that is L meters long.
1. To find how much the nylon costs per meter, take L = 1 (this means you are calculating the price of a piece of nylon rope that is 1 meter long):

2. To find how long a piece of nylon rope that costs $1.00 is, substitute into the equation p = 1:

(0, 4)
(-1, -3)
(2, -3)
For a 90 degrees clockwise rotation, the rule is (y, -x)
I think eight because if you add those days together they will play again in eight days so that they play on the same day.
Sorry if I got it wrong I tried and that's what counts, right?
